Mont. Code Ann. § 35-8-218

If a person required by 35-8-204 to execute any record or document fails or refuses to do so, a person who is adversely affected by the failure or refusal may petition a district court to direct the signing of the record or document. If the court finds that it is proper for the record or document to be signed and that a designated person has failed or refused to sign the record, it shall order the secretary of state to sign and file an appropriate record or document.
